Compact 2W xenon flash lamp module



The L13821 series is a lamp module that consists of circular circuit boards stacked in a cylindrical shape, giving greater freedom of design while maintaining a high output, high stability, and long lifetime.
Further miniaturization and operation on a 5 V mobile battery allow installing the L13821 series into various types of portable, compact equipment such as for water quality inspections and a vast range of other applications.
